Specification of Letters Patent. Patented J 11116 13, 1922. I

Application filed January 27, 1919. Serial No. 273,453.

To all whom it may concern Be it known that h IATTHIAs BRooK, deceased, late of Boston, in the county of Suitfolk and State of Massachusetts, invented certain Improvements in VVork-Positioning Mechanism for Upper-l orming and Other Machines, of which the following description in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for operating on boots and shoes; and is herein shown and described as embodied, for the purpose or" explanation, in an upper forming machine of the type shown, for example, in United States Letters Patent Nos. 1,1975437 and 1,197,439, granted Sept. 1%, 1916,'and No. 1.361.960, granted Dec. 14:, 1920, upon applications filed by Matthias Brock, such machines being designed "for shaping or molding the upper materials, including the heel sti'ttener. at the rear portion of a shoe to the sides of a metal torm corresponding to the heel end of the shoe and for inwardly Hanging the marginal portion of the stock over the edge of the bottom of said'itorm as a step preliminary to the lastingoperation, or in cheap grades of shoes. as a substitute for the "forming portion of the lasting operation.

As previously constructed or proposed, however, upper forming machines of the described type have not embodied shoe supportin and positioning mechanism adapted to take the shoes on their lasts, since no provision has previously been made to adapt the supporting and positioning means for accommodation to the variations in length and height of lasts and to the spring or pitchot the last bottom.

One of the objects oi the present invention is to provide a last and shoe supporting and positioning mechanism which is adapted for i use in a machine of the described type to enable the shoe uppers to be formed directly on their lasts. It will be recognized however, that in some of its novel aspects the invention is not limited to machines of that type nor to means forpositioning shoes on the last.

ith the above and other objects in view,

a feature of the invention consists in the combination with means for operating on a shoe of novel means for positioning and controlling ashoe in its relation to such operating means. In accordance with the illustrative embodiment of the invention, the

last and shoe supporting means is arranged for movement from a work receiving position to a position to present the shoe to the mechanism which operates upon the shoe, said means being also mounted for preparatorv movement with the shoe and last to a position in which the shoe is in a plane to co-operate with said mechanism, means being provided which are effective to lock the supporting means against movement from said plane prior to the presentation of the shoe for the operation of said mechanism. Thejillustrative forming machine organiza tion is also provided with treadle controlled power means for moving the last and shoe lengthwise into position for the operation of the forming mechanisim this means being yieldingly operated to adapt. the mechanism to different sizes of lasts and the consequent variation in the extent of. movement required to draw the last intoco-operative relation to the forming devices. The illustrated controlling mechanism for the last and shoe supporting means is also organized automatically to return the said supporting means to initial work receiving position to receive another last and shoe after a forming operation has been completed.

Features of the invention are also to be recognized in details of construction of the shoe positioning means.

These and other features of the invention will appear more fully from the following description of an illustrative embodiment ot the invention considered in connection with the accompanying drawings, and will be then pointed out in the claims;

In the accompanying drawings:

H Aspointed out in said. prior patents, the

forming '1nachine comprises a plurality of. duplicate units built lnto one machlne so a one-cycleclutch 12 on a shaft 13 driven through a continuously rotated pulley. This power operated driving shaft 13 imparts movement through gearing and under control of the clutch to the cam shaft 14 which operates through a lever 15, arod 16 and a work carrier 18' to draw the work back into the heel-embracing mold 4, the connection between the lever and rod, in accordance with the present invention, including a yielding element,'as shown, a leverconnected plunger 19 operating against a coiled spring 20 housed in a tubular portion 21 formed at the rear end otrod 16, and operating to position lastso'f different sizes and lengths in co-operative relation to the mold and wipers. When the work carrier 18 has been drawn back. as described, a cam operating against a roll on a lever 22, acts through link 23 to straighten toggle 24: and close the heel embracing mold 4 upon the work presented by carrier 18. The wipers 6. which are operated by a clutch controlled eccentric 25 on a counter shaft 26 geared to a driving shaft 28 continuously rotated by a pulley 30, are then caused to operate through a cam on shaft- 14: which acts against a roll carried by a pivot-ed arm 32 to which the lower end of a rod 3 1 is connected, the upper end ot this rod carrying a laterally offset plate 36 effective, when the rod is depressed by said cam. to move an arm88 latching the wiper eccentric clutch in inoperative position. 'Thc clutch is thrown in when said arm is moved and is effective to reciprocate the wipers continuously to shape the inturned flange of. the upper by repeated rubbing movements forthand back over the flange. After the mold 4L has been closed and the wiper clutch latch released, the cam F shaft 14: comes automatically to rest. lVhen the upper has been sufficiently wiped the treadle 10 is again actuated and the wiper clutch is withdrawn with the wipers opened, the heel embracing mold is opened, and the work carrier is moved away from said mold,

.member 18 arranged for movement into co-operative relation to the devices for operating upon the last and shoe in the manner above described. The rear or inner portion of this base 18 is formed with an upstanding casing 10 housing the heel pin standard and its operating parts and the front or outer end of the base is provided with an upstanding tubular holder 42 for the standard supporting the toe rest, whichholder is provided'with a laterally offset horizontal extension or plate d4 (Fig. 2) connected thereto by a fin 43.

The housing 410 is provided at its upper v end with a tubular guide 46 vertically alined with a bore formed in the base 18 and in which the flattened shank of the heel supporting standard 48 slides. This standard is supported from the base 18 as follows. The base, as previously stated, has a vertical bore alined with said shank. In this bore is slidably mounted a plunger 50 having a pin 1 and slot guiding and movement-limiting connection with the base and having a ref duced upper end projecting above the base and slotted. A squared sleeve or block 52 embracing the projecting end of said. plunger rests upon and is supported by the upper lace of the base 18 and is slotted in aline' ment with the plunger slot to permit the end of a controlling lever, later described, to project therethrough and to seat in the slot in the upper end of plunger 50. A plate 5% (see Figs. 2 and 41) is mounted between the walls of housing. 10 and is formed at its lower end with a slotted guide block 56 oilset toward the rear of the machine and having its base formed with a bore and with a lateral flange 58engaged by the bent upper endof a stop plate 60 rigidly connected with the sleeve 52. A heavy coiled spring 62 is interposed. between the lower face of said guide block and the upper face of sleeve 52 and yieldingly supports said plate and guide block, upward movement of the guide block being limited by the stop plate 60. Between the upperend of guide block 56 and the lower end of the tubular guide 46 the shank 48 of the heel standard is reduced in thickness, the lower end of this reduced portion sliding in the guide block 56 and being shouldered at 64 and provided below this shoulder with a reduced cylindrical extremity extending through the bore in the base of the guide block. A second and light-- er coiled spring 66 is mounted in the guide block 56 between said shoulder 64: and the base of the block and acts yieldingly to support the heel pin standard 18. The plunger 50 is moved upwardly, for a purpose hereinafter described, after the last carrier 18 has been drawn backwardly into co-operative relation to the mold 4 and wipers 6, by a slide 68 with which plunger 50 is alined when fully drawn backwardly, and which slide is moved upwardly when the connected toggle 70 is straightened by movement of link 72 through a lever 'Zetfulcrumcd on the machine frame and having a roll operating in a cam track as in the machines of said prior patents.

The upper end of standard 18 is enlargedto form a head 76 channeled to receive the base of a heel post 78 in the upper bifurcated end of which a heel pin 80 is pivoted for limited oscillatory adjustment to accommodate itself to the hole in a last 2. The post 78 is adjustable in ways formed in the head 76 lengthwise of the shoe and is held in adjusted position by means of a spring pressed toothed block 82 carried by the head and engaging teeth formed on the. base of the heel post. This adjustment is utilized in changing from one class of work to another, as from mens lasts to womens or childrens lasts, the permissible yielding of the spring connection 19, 20 in the last moving mechanism being intended to compensate for. the differences in length between the heel pin and the extremity of the heel end of the last in different sizes of lasts for the same class of shoes, and the lengthwise adjustment of the toe rest, later described, compensating for the differences in length of shoes.

To hold the heel post standard against upward movement from depressed (operating) position, to condition the standard for downward movement against the heavy resistance of spring 66; and to condition the standard for and automatically to return it to initial raised position after the operation upon the shoe, the following means are provided.

A locking block 104: bifurcated to embrace the plate 5 1 and loosely pivoted on said, plate has its rear end formed with an opening through which extends the shank of the standard 418, opposite side walls of said opening being formed with reverse double bevels best seen in Fig. 2, which, when the block is horizontally positioned, permit free vertical movement of the standard in both directions but which, 011811 the block is tilted on its pivot, prevent up and down movements of the standard relatively to the block in the respective reversely tilted positions of the block. This block is positioned and controlled through connections with a lever 106 having a pivot pin 108 (Figs. 1 and 2-3) journaled in one wall of the housing 410 and having its rear end inserted through the slot in sleeve 52 and loosely seated in the slotted upper end of plunger 50. At a point letween this plunger and the pivot pin 108, the lower end-of a rod 110 is pivoted to lever 106 and extends upwardly and loosely through a bore in a pivot block 112 journaled on a pin extending between the arms of the locking block 104: at th front end of the block, one arm of said block being recessed (Fig. 3) to provide space to receive the pivot block. At the upper and lower faces of the pivot block coiled springs 114; of substantially equal strength are sleeved on the rod and abut against washers 116 fixed to the rod at substantially equal distances from the respective faces of the block when the locking block 104- is in neutral or horizontal position. The pivot pin connecting rod 110 to lever 106 extends through the lever and at the outer side of the lever carries a roll 118 which extends through a vertical opening in the adjacent wall of housing 40 and abuts against the under face of a laterally offset flange at the top of a bracket 120 which is fastened to the side of the machine frame adjacent to the base 18, this under face acting as a cam and having heel standard controlling inclines 120 and 120 at its front and rear ends, respectively. and with an intermediate straight neutral portion 120*. In the outer position of the base 18 with the supported last and shoe out of co-operative relation to the heelembracing mold and wipers, the roll 118 rests against section 120 of the flange, the upper spring 1141 being compressed and the locking block 101- being tilted as shown in Figs. 1 and 2 to lock the standard 18 against upward movement from any position to which it is depressed through hand lever 98 as shown in F 1.

(lo-operating with the locking block and controlled through connections to the Same lever 106, are stop dogs 122 and 124: journaled respectivel; above and. below the locking block 10-1- on the plate 51 and having block engaging noses 123 and 125 (Fig. 2) respectively. Springs 126-428 anchored to thehonsing 40 and attached to the ends of these dogs normally tend to swing these noses into position for engagement with the upper and lower faces of the locking block to determine a neutral horizontal position of the block, these respective movements and the positions of the dogs being limited and determined by stop pins 130, 132 carried by plate 54:. The upper dog 122 in the position determined by the pin 130 prevents in swinging past a horizontal position it is shown in Figs. 1 and 2 and the lower dog 12-1: in the pos ion determined by the pin 1 :52 similarly prevents the block from swinging past the horizontal from its rerersely tilted position in which the standard 4-8 may more upwardly but-can only move (lownwardly against the resistance of the heavy spri g 62 to which the reversely swung block transmits the supporting strain tinough plate 51- and guide block 56. The members 22 and 121- thus permit such movements oi the block 16 1 them either of its locking positions as may he required to release the sttllldttld lthbut prevent the block from tilting so tar as to lock the standard in the reverse sense except as permitted by the mechanism which controls saidinembers.

'lilting of the upper dog against the tension oi" its spring 126 to inoperative position, and the tilting of said dog to operative position. through said sprin are permitted respectively by a rod 134: pivoted at its lower end toone side oi': the forward end of lever 106 and at its injiper end sliding freely through a pivot block 136 pivot-ally mounted on the dog 122 at its end opposite the stop pin 130. ihe.

end of the rod projects beyond the pivot block and has lined collar 138 thereon spaced above the upper face of the block in the initial tully outdrawn position 01. the last and shoe carrier 18 and providing for limited downward movement of rod 134 without turning the stop dog 122 From engagement with the pin 30 as the roll 118 oiulever 1.06 is released-by the part ot' the cam on bracket 120 in the movement oil he last and shoe into the heel-embracing mold. I.

Tilting oi? the lower dog-124tagainst the tension of its spring 128 to inoperative position and tilting of the dog through spring; to operative position are effected and are permitted respectively by a rod 1410 (Fig. 2) pivoted at its lower end to lever .166 in axial alinement with the pivot of rod 13% ot' the upper dog, and at its upper end sliding freely downwardly through a bore in a pivot block 1&2 joiirnaled on a pin extending outwardly from the dog 124: at its end opposite the stop pin .132. A fixed collar 1 141: on the rod abuts against the under side of the pivot blocl: 141-2 and holds the dog 1 in inoperative relation to the locking hloclt 104.- in the initial fully outdrawn position oi the last and shoe carrier 18 and as the carrier is moved rearwaiidly to cause the portion 126 of the cam to release the lever 106 to the balancing action of the springs 114 this collar is drawn away from block let-2 permitting spring 128 to turn the doe into engagement with the downwardly tilted front end of the locking block.

0 n the tilted position in winch a are effected and cordance with well known constructions of toe-rests. It is provided with a depending;

' :0 4: i Q spindle lee iieely shcnng through the hole of a tubular stem 1.50 rising from: plate which is slidable longitudinally in ways formed in the upper face of a transversely invinging base 15%. The stem, has'its upper end flanged and embraced by the overlappingedgeot a plate secured to the bottom edge-of a collar 1.56 said collar enclosing and-confining between it and said flanged end, a nut threaded onspindle 1&8 This collar 156 is also provided with an up standing; boss through the smooth bore of which the stem 1 18 freely moves. W-hen'the collar. is manually turned the nut is turned with it and acts to adjust the stem and toe rest vertically. The plate 152 is retained in longitudinally adjusted position by a set screw 153 fitted in a boss laterally outstanih from the base 154: and engagingthe side edge of the plate. The base 15 1 is pivoted on a boss at the rear end of the laterally extending head 158 of a. toe restsupporting standard 160 having a reduced tubular lower portion 162 fitting in the socket oi the holder 412 and normally raised in said socket by a coiled spring 1641 seated in said tubular portion and engaging at its lower end the base of the socket in holder 42. The trout of the head 158 of the toe rest standard is provideiil with a guiding edge 165 fOllDGCl as an arc with the pivot of the base 1541 as center and serving in co-operation with. a spring pressed frictional plug 1.66 carried by the base and engaging said edgerto hold the base in its transversely adjusted position. It will be evident that after the toe rest and its supportingmeans have been adjusted to receive a last and shoe'positioned on the heel pin 86, the toe rest may be depressed eo'incid'ently'withthe heel pin and against the resistance of the upholding coiled spring 164- atthe base of standard 160.

To hold the toe rest standard in depressed position and subsequently to release it, the following mechanism is provided. To the head 158 of the standard is attached the upper end of a depending bar 168 (Fig. 2) which is laterally ollset from the standard 160 and holder 12- and is vertically slidable with the standard. This bar slides freely through a correspondingly shaped recess in the horizontal plate 4:4: offset from holder 42. A. locking plate 170 is seated on the holder 12 and has one edge slotted to embrace the fin 4:3 and adjacent to said slot is formed. with an opening through which the bar 168 may slide. opening facing the opposite faces of bar 168 are downwardly and inwardly beveled and are effective, when the front end of the plate is tilted upwardly, frictionally to grip and prevent upward movement of the depressed bar 168 and standard 160 while permitting downward movement of said parts. A coiled spring 172 (Fig. 2) interposed between the front end of the locking plate and a lug 174 offset from the holder 12 normally tilts said plate to a position permitting depression of the bar 168 and its standard but preventing upward movement thereof as described. This tilted position of the locking plate is the normal position of the plate when the carrier 18 is fully outdra-wn. The plate is controlled by movement of the carrier 18 as follows:

A. link 176 (Fig. is pivotally attached at its upper end to the spring pressed end. of the locking plate and has slidably mounted. thereon adjacent to its lower end a collar 175 which is pivotally connected to the front end of a controlling lever. 178 standing out side of the housing 40 at the'side opposite to the heel pin controlling lever 106 and journaled intermediate of its ends on a pin laterally outstanding from the base of holder 42. A nut 177 adjustably mounted on the lower end of rod 176 acts as an abutment engaged by the collar 175 in moving downwardly from the position shown in Fig. 2'. The rearward end of lever 178 carries a roll 180 which, inthe fully outdrawn position of carrier 18, stands below and slightly forwardly of the front end of a finger 182, which front end underlies the upper horizontally flanged edge 184 of a bracket 186 adjustably fixed to the machine frame adj acent to the front end of carrier 18 as best seen in Fig. 2. This finger is pivoted intermediate of its ends to the rear end of said bracket and has a downwardly bent rear end 183 to which a spring anchored to the bracket is attached. This spring is effective normally to tilt the front end of the finger upwardly against the bracket flange 184tand permits the roll 180, when the carrier is drawn inwardly, to engage the lower edge of the finger and to tilt the rear bent end 'of the finger upwardly and to ride beyond said finger end which is subsequently pulled down by its spring to a position below the roll.

The pivoted finger, therefore, yields during the rearward or indrawing movement of the carrier to position the last in operative relation to the forming devices and does not act through lever 178 to change the position of locking plate 170. On the reverse or outward movement of the carrier from The sides of this working position, the roll 180 rides over.

the upper edge of the rear bent end of the finger (which cannot yield downwardly since its front end engages the flange 184C) and is guided over the top of said flange 184k, thereby swinging the front end of the lever 17 8 downwardly until nut 177 is engaged, and thereafter imparting further movement to the lever sufficient to tilt the evident that springs 62 and 66 of the heel support and the spring 16 1 of the toe rest initially hold the last seated on the heel pin and toe rest elevated above the plane which they occupy when the last and shoe are in co-operative relation to the forming means. This plane is established by determinately depressing the last and shoe and in holding the last supporting means in the position to which they are depressed. The mecha nism for depressing the last and shoe and its sup-porting means as herein shown,'comprises a bracket 84 secured to and upstanding from the top of the machine frame-and having a guide 86 outstanding over the heel seat of a supported last in the outer position of the last carrier 18. A vertically movable plunger 88 slides through the guide 86 and has its lower end pivoted to a depressor plate 90 intermediate of its ends, said plate having an upstanding lug 92 at its rear end and having sole engaging feet at its opposite ends. A coiled spring interposed between the plunger and said lug normally tends to hold them separated and a set screw 94; projecting from the lug toward the plun ger limits and determines by contact with jacent to its fulcrum point which carries an 1 adjustable set screw 100 arranged to engage the arm 85 when the lever is depressed determinately to limit the extent to which the sole on the last 2 may be depressed by the plate 90. The set screw will, of course, be adjusted to aline the sole with the wipers and since the last is yieldingly supported and may be depressed, the set screw 100 will always position the sole in the proper plane for the action of the wipers. A coiled spring 102 connects the hand lever 98 with bracket 84: and normally holds the lever and depressor plate elevated above a supported last and shoe.

In the operation of the machine, the hand lever 98 is released when the last and shoe have been depressed to the plane predetermined by the set screw 100, and the operator subsequently depresses treadle 10, starting the machine, the link 16 drawing the carrier.

inwardly to bring the heel and end of the last against and within the embracing mold 4: which. is immediately closed and the wipers 6 operated. These wipers, as described in said prior patents and application, are first fully closed over the heelseat of the shoe and thereafter are continuously rcciprocated without being fully'retractedso that they remain over the sole of .the shoe and give a continuous series ct rubbing upper flanging and compactingmovements until the treadle 10 is again actuated, this actuation resulting in completely retracting and stopping the wipers, opening the heel embracing mold and sliding the last carrier 18 outwardly in the sequence named as fully described in said prior patents. After the last and shoe have been depressed in the manner described, the locking block 104 int-he tilted position indicated in the drawings acts automatically to prevent reverse upward movement of the heel post standard during the'rearward movement of the carrier to present the shoein operative relation to the mold 4 and the wipers, the

release of the lever 106 by the part 120 of the cam simply permitting the springs 11a, to assume a balanced relation without atljectber 122. After the shoe h as been clamped by r the closing of the mold 4; round the heel end, the slide 68 is moved upwardly, as hereinbefore described, this slide serving to elevate the plunger 50 and through the engagement the level .106 to swing the rear end of this lever farther upwardly and through the lower spring 114-. to tip the lockingbloclt 10% into its reverse locking positi on,the lever" actlng simultaneously through the rod 13st to swing the stop member 122 out of its limiting pOSltlOIL in such manner as to-perinit this movement of the member 104 to its reverse position. VVith-the locking block 10 1 thus tilted reversely from the positionindicated 1n the drawings, the standard 48 is locked against downward movement relatively to said block but is subject'edto the control of the comparatively heavy spring 62 which bears upwardlyagainst the member56 on which the locking block is supported, in place of thecomparatively light tension 01' the spring 66against which the standard was moved downward manually, the spring 62 being subjected to increased tension by the continued upward movement of the plunger 50 acting on the sleeve member A more effective yielding support tor the 1 shoe againstthe downward pressure of the wipers is thus afforded.

After the operations on the shoe have been completed and the work is released by the return of the mold and the wipers to starting position, the spring 66 may act to elevate the standard 48, the latter acting by its trictional engagement with the locking block 104C to tilt the block against the light tension of the lower controlling spring 114. to ahorizontal neutral position past which it is not permitted to tip by the lower stop member- 12 1 which is still maintained in its operative limiting position. When the plunger 50 is permitted to move downwardly by the re tractive movement of the slide 68, the release of the lever: 106 permits the springs 11 1 again to assume a balanced relation. As the carrier 18 starts to move outwardly in its return to starting position, the roll 118,i't the locking bloclr10a has not already assumed a neutral horizontalposition in re sponse to the action of the spring 66 on the standard 18 en ae'esthe uaturne'd )art 120 a a l of the cam, and the lever 106 is thereby swung in thedircctionto return the block to such. neutral position, the stop members 122 and 124 then being effective at the oppo wherein the lower stop member 124 tilted out oi its limiting position and the locking block 104 is so inclined as topermit downward movement of the heel post standarcl when the next shoe is mounted t' hereonand depressed by the action of the lever 98. As above stated, such depression of the shoe is or the upper end portion of thilsplunger with against the tension ofthe light spring 66, the locking block being turned by its itrictional engagement withthestandard a suflicient distance to permit the standard to slide through the opening in the block and the movement of. the locking block past a neutral position being prevented by the action of the upper stop member 122. y The operation of the means whereby the to movement of the carrier 18 has already beencrrplained in connection with. the descriptlon of that portion of the structure {toe post is locked against upward movement and 1S subsequently released in time relation and will be clearly understood without further explanation.
